Hi,
I just bought a MacbookPro5,1 and having difficulties with the onboard HDA chipset.
* No sound can be heard of it if model= is not set to mbp3: [ 12.009422] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... http://www.alsa-project.org/db/?f=4b2f257e72523bccafd3ace1d3c7044fb5f09ff8
* If model=mbp3 is given, it's possible to get sound from it but with many annoying problems:
- You have to switch to 6ch mode for getting sound, doesn't work with 2ch mode, - The sound quality is very very bad, - Once you switch to 6ch mode, - You have to increment the volume of *Line-in* to have hearable sound from *internal speakers*, - You have to increment the volume of *Front* to have hearable sound from *headphones*, - The two controls are not mutually exclusive, you have to mute one of them, if you're using the other.
And then I decided to play with hda-analyzer. After a bit of playing, I started to get sound from the board without the model=mbp3. But the mixers are still behaving somewhat strange. Before actually reporting any feedback on what I've switched and did, what do you suggest me to do? Is setting the model= to something, something similar to what I was doing with hda-analyzer?
Thanks Ozan Caglayan
